I-55 flooded at County Line Road in Burr Ridge – as the downpour soaked the area.

Cars were able to maneuver through it, but there were plenty of delays.

Many residential streets in Willowbrook were also flooded last night as the rushing runoff had nowhere to go.

The storms first hit the far western suburbs and DeKalb early in the evening, bringing marble-sized hail and winds topping sixty miles an hour.

Those winds toppled at least one semi-trailer and several smaller trailers.

There were also reports of power outages.

In Aurora, the sudden downpours quickly flooded viaducts and underpasses.

At least two cars got stuck in standing water at one viaduct.

The severe weather prompted officials to cancel more than 115 flights at O’Hare International Airport, according to the Chicago Department of Aviation. As of 8:30 p.m., officials had halted all flights at Midway Airport.
